Aspirin at very ultra low dosage in healthy volunteers: effects on bleeding time, platelet aggregation and coagulation.

Aspirin at very ultra low dosage was tested in healthy volunteers (n = 20) in a randomized, double-blind and placebo-controlled trial. The results showed a bleeding time reduction (p less than 0.05) in volunteers having previously ingested aspirin. Platelet aggregation on platelet-rich plasma was not statistically modified after aspirin ingestion. Thrombin clotting time was always higher (p less than 0.05) in the treated group.
